How to resolve the error "Intel Rapid Start Technology Manager. Your system does not have IRST enabled" after a memory upgrade.



Why you receive the error "Intel Rapid Start Technology Manager. Your system does not have IRST enabled" after a memory upgrade and how to resolve the issue.


Why is this error occurring?

You will receive this error on systems that have Intel® Rapid Start Technology (IRST) enabled (Either a Single Solid State Drive [SSD], or a Hard Disk Drive [HDD] and an SSD or Mini-SATA [mSATA] SSD drive installed) and you change the amount of memory installed in the system without making changes to the IRST configuration.

This issue is caused by the amount of memory (RAM) installed in the system exceeding the size of the rapid start Intel® partition. When the IRST driver cannot cache all the system memory to the rapid start partition because you increased the amount of memory in the system, this error occurs.


How do I resolve the error?

The issue is resolved by increasing the IRST partition to match the size of the increased memory. (If after the memory upgrade you now have 8GB of RAM, you will need an 8GB IRST partition to match.) IRST is disabled if the system memory is increased above 8 GB.

NOTE: Intel® Rapid Start Technology will automatically be turned off if the Memory capacity is expanded beyond 8GB, a system or HDD password is enabled, the Hard Disk configuration has changed or the Block Sleep setting is enabled.

The IRST partition on the hard drive is protected, so deleting it and re-creating it takes a little bit of effort. Follow these steps:

Caution: You are cautioned to use extreme care in choosing the partition to delete and ensure that it is the correct partition. If you fail to select the correct, partition you may cause unrecoverable data loss. If you do not feel comfortable with this process, it is recommended you contact Dell Support or if you desire, a local technical professional.
  1. If you are still receiving the error message, power down the system, remove the added RAM module, then reset BIOS defaults and reboot. The error should be resolved.
  2. Click the Start Pearl, type: diskpart in the search box, then Click Diskpart from the programs menu, this will open a command window. A prompt may appear: "Do you want to allow the following program to make changes to this computer?". If this appears, select "Yes". Then a command window should appear.
  3. Type: "List Disk" then press the then press the Enter key. This will list the disks in the system. In a single SSD drive system, you will want Disk 0; in a system with a HDD and SSD you will want Disk 1 (the SSD).
  4. Type "Select Disk #"then press the then press the Enter key. # should correspond with the drive letter you are needing to work on. 0 for a single SSD, 1 for a HDD and SSD. If you have more drives than discussed, your SSD may be a different drive.
  5. Once you have selected the disk, then type: "List Partition" then press the Enter key, to display the partitions. On a single SSD drive, this should be partition 4, OEM and will be the size of the RAM originally installed in the system (2 GB or 4 GB).
  6. Type: "Select Partition #"then press the then press the Enter key. # should correspond with the 2 or 4 GB OEM partition we want to delete.
  7. You should have a DISKPART PARTITION #> prompt type: "DELETE PARTITION OVERRIDE" then press the then press the Enter key. (This will delete the dedicated hibernate partition for Intel® Rapid Start)
  8. Type: "List Partition" then press the Enter key, and confirm that the 2/4 GB OEM partition has been deleted.
  9. Type: "Exit" then press the Enter key to exit diskpart.
  10. Click the Start Pearl, right-click Computer, click Manage, to open Computer Management, then click Disk Management on the bottom of the left column. This will open the disk management applet.
  11. On a single SSD system, Disk 0 should have 3 or 4 partitions and 2 or 4 GB of un-partitioned space, on a HDD, SSD system, you should have a Disk 1 with 2 or 4 GB of un-partitioned space.
  12. Immediately left of the un-partitioned space should be a healthy partition, click the partition to highlight it, then right click and select "Shrink Partition". If you have 2 GB of un-partitioned space, shrink the healthy partition 6144 MB (6GB) to make a total of 8 GB un-partitioned space. If you have 4 GB un-partitioned, then select 4096 MB (4 GB) then click the "Shrink" button to complete the process.
  13. Once you have 8 GB of un-partitioned space, close Disk Management and Computer Management, and reopen diskpart.
  14. At the diskpart prompt, again type "List Disk" then press the Enter key and again determine the disk we are using, then "Select Disk" then press the Enter key to select the disk to create the new partition.
  15. Type: "create partition primary", and press the then press the Enter key. This will create a new 8 GB partition.
  16. Type: "set id=84 override", and press the then press the Enter key. Then type "List Partition" then press the Enter key, and confirm that the 8 GB OEM partition has been created.
  17. Type: "exit" then press the Enter key to exit diskpart, if the command window remains open, type "exit" then press the Enter key a second time to close the command window.
  18. Power off the system, install the upgrade memory and reboot into windows. The error should no longer occur.
